He won’t leave my head

He won’t leave my head…. I thought I was over him but last night I had a dream about him. The dream was everything I ever wanted and he would keep popping up in it. I moved to Japan for a trimester for school, it was amazing! I made two friends who I felt like I had known forever and I woke up everyday excited to see what awaited me. But, every time I would be going about my business Ben would show up, just walking away from me but he would always look back at me as I did the same with him. If I tried to go towards him anything would stop me. Right before I woke up I was on the swings with my two friends and out of nowhere he burst out the doors and ran away. Why can’t my brain just forget him…..
